Juan Francisco Lopez-Sanchez, right, is led into the courtroom by San Francisco Public Defender Jeff Adachi, left, and Assistant District Attorney Diana Garciaor, center, for his arraignment at the Hall of Justice in San Francisco in this July 7, 2015, file photo. The parents of Kathryn Steinle filed a wrongful death claim Tuesday, Sept. 1, 2015, alleging that the San Francisco Sheriff's Department is to blame for releasing an illegal immigrant from jail despite a federal "detainer" request to keep in custody for possible deportation proceedings. A claim is usually a precursor to a lawsuit. (Michael Macor/San Francisco Chronicle via AP, Pool, File)
